Background. The detoxified TLR4-ligand Monophosphoryl Lipid A (MPLA) is the first approved TLR-agonist used as adjuvant in licensed vaccines but has not yet been explored as part of conjugated vaccines. Objective. To investigate the immune-modulating properties of a fusion protein consisting of MPLA and Ovalbumin (MPLA : Ova). Results. MPLA and Ova were chemically coupled by stable carbamate li...

BACKGROUND Sublingual immunotherapy (SLIT) allergy vaccines have an excellent safety profile, but opinions vary on their efficacy, and treatment regimens are often lengthy. This study assessed the effects of the Toll-like receptor 4 agonist monophosphoryl lipid A (MPL®) on safety/tolerability and clinical and immunological efficacy when combined with grass pollen SLIT formulations in treating p...

Software product lines (SPLs) enable an efficient development of similar programs based on a common code base. Although the number of SPLs in practice increases, the development and maintenance of an SPL is still challenging. In detail, a developer has to consider a huge amount of variability in each step of the development cycle that can become unmanageable. Therefore, multi software product l...

objective(s):tumor-associated antigen (taa) subunit-based vaccines constitute promising tools for anticancer immunotherapy. however, a major limitation in the development of such vaccines is the poor immunogenicity of peptides when used alone.the aim of this study was to develop an efficient vaccine delivery system and adjuvant to enhance anti-tumor activity of a synthetic her2/neu derived pept...

Vaccines can greatly reduce the spread of and deaths from many infectious diseases. However, many infections have no successful vaccines. Better understanding of the generation of protective CD8 memory T cells by vaccination is essential for the rational design of new vaccines that aim to prime cellular immune responses. Here we demonstrate that the combination of two adjuvants that are current...

BACKGROUND a new range of allergy vaccines has been developed by the introduction of a relatively new Th1-inducing adjuvant known as 3-deacylated monophosphoryl lipid A (MPL). MPL adjuvant is of natural origin, derived from the lipopolysaccharide of Salmonella minnesota R595. This adjuvant is incorporated in a glutaraldehyde-modified pollen extract adsorbed to L-tyrosine (Pollinex Quattro). A m...

Two million new cases of leishmaniasis occur every year, with the cutaneous leishmaniasis (CL) presentation accounting for approximately two-thirds of all cases. Despite the high incidence rates and geographic expansion of the disease, CL remains a neglected tropical disease without effective intervention strategies. Efforts to address this deficit have given rise to the experimental murine mod...
